Buy tungsten carbide rod and tungsten carbide plate
15th International Conference on pulanxi in Austria of Rohr Ishmael roett WaHer Schwarzkopt Haus Conference Center in the city, 500 delegates from 40 countries and regions participated in the meeting.
At the meeting, tungsten carbide rod, ome experts exchange progress research on hard materials.
Ultrafine and nano-grained tungsten carbide plate was discussed, as well as developments in cutting tools for extreme conditions. Germany Mr h c Starck g Gill,tungsten carbide plate, in common with other manufacturers use commented on the submicron tungsten carbide rod in over a dozen years of the larger developments, and noted that factors affecting the alloy performance improvement, tungsten carbide rod development of ultra-fine grained materials play an important role. Tungsten carbide (WC) powder particle size has been reduced to sub-micron levels, even as low as 0.2 μ m. Application of sub-micron grained tungsten carbide rod, g Gille believes that, in 2000, the world (including China) between the production of sub-micron grained cemented carbide in11500~12500t, total 40% of tungsten carbide plate production. Among them, carbide drill bits, tungsten carbide plate, carbide milling cutter accounted for the largest share, amounted to 60%, about 7000~7500t, but these applications are still growing rapidly; electronics with micro-drills, 13% and wear parts, circuit boards, scissors, paper cutting knife, non-cutting shaping mould for plastics, dental tools, tungsten carbide plate such as 18%; 4% of woodworking tools, metal cutting blade 5%. Processing of micro-drilling for printed circuit board is first and extremely important applications of submicron tungsten carbide rod, one of its consumption has been increasing rapidly. Over the past 15 years, the speed has increased from 80000r/min to 180000r/min for micro-drilling, tungsten carbide plate, drill diameter from 500 μ m reducing to 200 μm.The latest generation of micro-drilling diameter has been reduced to 70 μm.
